Each challenge carries a 86 bit nonce derived from the identity key and the epoch seed, so no two identities ever answer the same question. A bank of pre-written answers therefore has nothing to key against, and filling 112 aliases means authoring 112 texts that each match their own nonce. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"MAdjpcwCGjsN4PHw362VsPta7p8qRxQSSJStH8vZUx33djS3hfTLATbCEUr2XSo4MbxoW5P8GXNTEDpF8xws4B1"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T17:58:31.510Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
